Another method of pipe production is the spiral welding method. In this method, steel pipes are produced by spiral welding of sheets in different thicknesses, which is known as SPIRAL in the industry literature. The method of producing spiral pipes is very simple, the steel sheet is rolled out of the opening of the pipe rolling machine in the form of a roll and welded by two electrodes. Steel spiral pipes are generally in large sizes to meet the needs of the pipe. It is produced with a sheet width of more than 10 meters, therefore, using this method, it is possible to produce and supply pipes of any size that is needed in the pipping industry
